This reminds me of a legendary marksdwarf I once had. I cross trained him to legendary hammerdwarf as well. Anyway, I knew it was about to be sieging time (savescum, I know. Really, I did worse after the savescum, but the first time a dwarven caravan's mule got clipped in the stomach with a bullet and caused the whole thing to flee. Reset and switch to beforehand, lose two dwarves instead of none, but keep the caravan). Anyway, back to the marksdwarf. He was legendary in that, using masterwork ruby encrusted steel bolts [25] and a masterwork crossbow.
He runs out into a line of about 18 goblin bow/crossbowgoblins, including a legendary local leader, along with a good deal of hammer and wrestler goblins. He got there before anybody else, thanks to his absurd agility. I write him off as a loss. Boy, was I wrong.
The guy spits out his crossbow bolts like machinegun fire, taking down twenty goblins with 25 bolts. He runs straight into a line of bolts and rushes through the other side, with NO WOUNDS. Literally 12 crossbow bolts ran straight through where he was, stopped, and dropped to the ground. He proceeds to run straight into a pack of about 20 more goblins, all melee. Once again, I write him off as a loss.
I've never seen so much blood. Jeesus christ, that guy was ecstatic for a year just on the slaughter, then suddenly dropped straight to miserable (wife and many friends died in ANOTHER siege while he was out with a sparring (with swords) injury he promptly recovered. I had reassigned him a crossbow while he was wounded (light spinal injury, such a waste of a good dwarf). He promptly tantrums and proceeds to annihilate most of my military, and a good deal of civilians before calming down.
